Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684678, here are decompositions:

157 + 8684521 = 8684678
199 + 8684479 = 8684678
241 + 8684437 = 8684678
271 + 8684407 = 8684678
337 + 8684341 = 8684678
349 + 8684329 = 8684678
421 + 8684257 = 8684678
547 + 8684131 = 8684678

Showing the first eight; more decompositions exist.
